My husband and I play around a lot with the Dom/Sub role. I know that he wants me to be the Dom sometimes. But I have NO idea what to do to a male. I mean he wants me to talk nasty to him. (Could anybody give me some really good lines?) We are not extreme about this. So he isn't making clean up the toilet with my tongue or anything. Everything we do happens in bed. So I know he won't want me to do extreme things to him. If you guys or gals have any advice or examples, let me know. I appreciate you time.

I can see the problem. With my husband and myself, we love it when he's dom and I am sub. We don't do it by talking nasty, but for example having him order me to do things like sucking him, do positions, ... Maybe you can try that sort of stuff ?

it's not that difficult , with my husband i'm the dom most of the time, you just have to use certain tone of voice (ordering) and you control the position and timing and the rhythm,
you can try holding down his hands while you're on top or even tie him up
or you can seduce him, get his soooo excitd and then tell him to beg for it
hope this was useful

I guess it depends on how out there you want to get. You could stick a finger in his butt, call him a fag for letting you do that, dress him in women's clothes, tie him up, give him a handjob and tell him he's not allowed to come, then beat him for coming. You could sit on his face and suffocate him with your vagina.
